Answer:

the sum of the angles pythagorean theorem is a^2+b^2=c^2

Also, the angles of a triangle will add up to 180 degrees

this practice is most commonly found in right triangles

) Thirty percent of the students in a management class are graduate students. A random sample of 3 students is selected. a) Usin

adell [148]

Given Information:

Probability of success = 30%

Sample size = n = 3

Variable of interest = x = 2

Required Information:

Probability of exactly 2 graduates = ?

Answer:

Probability of exactly 2 graduates = P(2; 3, 0.30) = 0.189

Step-by-step explanation:

The given problem can be modeled as a binomial experiment since a random selected student can either b graduate or not therefore, there are only 2 outcomes. Each trial is independent and the probability of success is not changing from trial to trial. The number of trials in also fixed.

We know that a binomial distribution is given by

P(x; n, p) = nCx pˣ (1 - p)ⁿ⁻ˣ

Where p is the probability of success and 1 - p is the probability of failure, n is number of independent trials and x is the variable of interest.

For the given problem, we know that x = 2, n = 3 and p = 0.30

P(2; 3, 0.30) = 3C2*0.30²*(1 - 0.30)³⁻²

P(2; 3, 0.30) = 3*0.30²*(0.70)¹

P(2; 3, 0.30) = 0.189

Draw a polygon with the given conditions in a coordinate plane of rectangle with a perimeter of 20 units

Anarel [89]

Question says to draw a polygon with the given conditions in a coordinate plane. It is talking about Rectangle with perimeter of 20 units.

So we can use formula of perimeter of rectangel to find it's possible dimensions.

We knwo that perimeter of the rectangle is given by 2(L+W)

where L is lenght and W is width.

Given perimeter is 20 so we get:

2(L+W)=20

L+W=10

L=10-W

So basically we can use any number for W which can be from 0 to 10 as side length can't be negative.

Let W=4

Then L=10-W=10-4=6

Hence we just have to draw a rectangle having length 6 and width 4.

So the final answer will be picture in the attached graph.

11 is 40% of whst number

SOVA2 [1]

11 is 40% of 27.5

Change the percentage to a decimal by dividing it over 100:
$\frac{40}{100} = 0.4$

Divide 11 over 0.4:
$\frac{11}{0.4} = 27.5$
